ABSTRACT:
A linear guide includes rolling bodies that are inserted into mutually corresponding grooves of mutually guided parts. The guide surfaces for the rolling bodies are partially formed by plane surfaces of rotatable beveled round rods that are positioned in the grooves. The linear guide is constructed as a double guide on both sides with respectively two spaced-apart guide grooves on mutually opposed sides of the mutually guided parts. Because the guide surfaces are partially formed by the plane surfaces of the rotatable beveled round rods, wedge angles between the mutually guided parts are compensated. Manufacturing technical requirements regarding the matching of the distances of the guide grooves to each other are thereby greatly reduced.
